Definições Yealink

Siglas e termos explicados

Yealink explora as explicações simplificadas de Yealink sobre termos comuns de comunicação empresarial em relação à aplicação de três principais dispositivos de comunicação: telefones IP, equipamentos de videoconferência e fones de ouvido executados em Microsoft, Zoom e outros sistemas, no trabalho empresarial.

O que é Video Fence?

Atualmente, cada vez mais salas de conferência usam paredes/divisórias de vidro como fundos. Ao usar a função Al, é fácil selecionar não participantes, afetando a experiência de visualização ideal de participantes remotos. Cerca de vídeo Yealink surgiu. Ao limitar o alcance de detecção da câmera (que pode ser ajustado livremente de acordo com as necessidades), alguns fatores de interferência que afetam a precisão do rastreamento, como retratos pendurados na parede, reflexos na parede de vidro, etc., são removidos. Dentro do alcance selecionado, a função Al operará conforme o esperado.


Processo de implementação da função Video Fence


Lente única:

Yealink usa funções trigonométricas baseadas em parâmetros da lente para calcular a profundidade, ou seja, a distância entre a câmera e o participante, e o método de relação proporcional para calcular a largura do participante em relação à câmera, ou seja, a distância real entre a pessoa e a linha central da imagem.


Use uma lente de foco fixo para detectar todos os quadros de cabeça e filtre de acordo com a profundidade e a largura definidas pelo usuário. Pessoas fora do alcance de detecção são enquadradas por quadros vermelhos na imagem, e pessoas dentro do alcance de detecção são enquadradas por quadros verdes.


Lentes duplas:

A profundidade é calculada usando funções trigonométricas, e a largura é calculada usando funções de ajuste.


Duas lentes de foco fixo: a lente dupla é composta por duas lentes de foco fixo (como SmartVision40), e a função Video Fence é implementada de acordo com a lógica de implementação de lente única mencionada acima.


Lente de Zoom + lente de foco fixo: A lente dupla consiste em uma lente de zoom e uma lente de foco fixo. Uma lente de zoom de alta definição com ampliação variável é usada para detecção, e os resultados da detecção são então mapeados para a lente de foco fixo para garantir a precisão, e a lógica de implementação da lente de foco fixo é reutilizada para implementar a função Video Fence.




Faixa ajustável de cerca de vídeo


O intervalo de ajuste de profundidade e largura da função de cerca de vídeo muda de acordo com o alcance máximo visível da câmera e pode cobrir basicamente salas de conferência médias e grandes da Microsoft. A profundidade e largura que diferentes câmeras podem cobrir (ou seja, o intervalo ajustável da Cerca de Vídeo) são detalhadas na tabela abaixo.

Os parâmetros entram em vigor em tempo real e permanecem válidos após a reinicialização até serem modificados e salvos novamente na próxima vez.



Exibição de efeito

A função Video Fence é eficaz no modo Enquadramento automático/Rastreamento de alto-falante/Multifoco.

A função Video Fence em Auto Framing é baseada em uma lente de foco fixo. A função Video Fence em Speaker Tracking é baseada em uma lente de foco fixo. A função Video Fence em Multi Focus é baseada em uma lente de zoom.
